Document Type and Number:
Japanese Patent JP2589882
Kind Code:
B2
Abstract:
A system and process for sizing wood chips to provide a flow of wood chips which are acceptable for feeding to a digester of a pulping system. A flow management screen station is rovided which divides an incoming unacceptable flow (F0) into two fractional flows (F1, F2), neither of which is acceptable for feeding to the digester. One of the output flows from the flow management screen is concentrated in oversized and overthick chips compared to the incoming flow. The other output flow is concentrated in undersized chips and particles compared to the incoming flow. The output flows from the flow management screen are then fed to second and third screens (16, 14) which separate "overs" and "unders" from the respective flows to provide acceptable flows to the digester.
